What is an Echo Sounder and How Does it Work?
Echo Sounder Definition
An echo sounder is a sonar (Sound Navigation and Ranging) device used to determine water depth by transmitting sound waves. These waves leap off objects like the seabed or underwater boundaries and return to the device. The echo sounder calculates the intensity by measuring the time it takes for the sound waves to go back.
